Installation Process

Here we have a sample of our technicians installing an interlock patio for one of our clients. In this photo the excavation has already been completed and the backfilling of the Granular ‘A’ (gravel) base had begun. We excavate to 12” for our interlock installations, 20" for driveways. On all our jobs prior to the granular ‘A’ we install a geo textile membrane, it’s the “black blanket” you see in the photo. This will prevent frost movement and settling by acting as a barrier between the granular ‘A’ and the sub soil.
The next step is to compact the base. We do this in multiple layers to make sure the base is solid with no air pockets. In this photo you will see one of our technicians compacting the Granular ‘A’. You will notice that the 6x6 western red cedar poles have already been installed for a future pergola.
Once the base is prepared we are ready to install the interlock according to the landscape design that was provided for you. After the interlock is laid we will complete the cutting required. We then install a snap-lock or invisible edge to prevent the interlock from separating. We are now ready to install the stabilizing sand. Sand is what helps to lock all the stones in place. Stabilizing sand is beneficial for your interlock because it will minimize weeds, ants and erosion. We will then do any final touch ups like sod patching and clean up. Now its time to sit back and enjoy your new retreat for the rest of the summer.
